断层是煤矿开采中常见的地质构造之一,工作面在通过断层带时,顶板往往比较破碎,支护难度增加,容易出现支架倾斜、端面冒顶等情况。如何做好工作面过断层期间的管理,是一个值得探讨的课题。本文以某煤矿1208综采工作面过ND42断层为例,对工作面过断层期间的管理进行了探讨。
Fault is one of the common geological formations in coal mining. When the working face passes the fault zone, the roof is often broken and the degree of support is increased, and the slope of the support and the roof fall easily occur. How to do a good job management during the fault period is a subject worth exploring. In this paper, taking the ND42 fault in 1208 fully mechanized mining face of a coal mine as an example, the management during the fault crossing of the working face is discussed.
